Abstract
The possibility of producing multilayer billets by wire arc additive manufacturing (WAAM) technology with layer-by-layer forging using Cr20Mn5Ni4Mo2.5Cu3N0.3 flux-cored wire of 1.6 mm diameter as electrode material is investigated. The applied method resulted in the production of a weld metal with austenitic-ferritic structure (δF ≈ 1.5 vol %) without defects, which demonstrates a good combination of strength and plastic properties (σB = 960 MPa, σ0.2 = 670 MPa, δ = 35%).
用含氮奥氏体药芯焊丝脉冲MIG焊接分层合成钢坯
研究了以直径1.6 mm的Cr20Mn5Ni4Mo2.5Cu3N0.3药芯焊丝为电极材料，采用线弧增材制造（WAAM）逐层锻造制备多层钢坯的可能性。采用该方法制备的焊缝金属具有奥氏体-铁素体组织（δ f≈1.5 vol %），且无缺陷，具有良好的强度和塑性结合性能（σB = 960 MPa, σ0.2 = 670 MPa, δ = 35%）。
